# 注意替换命令中的安装路径和contrib的路径
cmake -A x64 -DCMAKE_INSTALL_PREFIX= -DOPENCV_EXTRA_MODULES_PATH=/opencv_contrib/modules -DBUILD_DOCS=OFF -DWITH_CUDA=ON -DCUDA_FAST_MATH=ON -DCUDA_GENERATION=Auto -DWITH_TBB=ON -DBUILD_opencv_python2=OFF -DBUILD_opencv_python3=ON ..
# Debug
cmake --build . -j 8 --config Debug --target install
# Release
cmake --build . -j 8 --config Release --target install
CUDA_GENERATION=Auto选项会针对本地GPU生成代码(否则生成所有支持架构的代码),可以加快编译速度。
例如:以ffmpeg
的动态库为例说明
opencv_videoio_ffmpeg.dll
opencv_videoio_ffmpeg_64.dll
ffmpeg_version.cmake
找到opencv/3rdparty/ffmpeg/ffmpeg.cmake
文件,定位到https下载链接这一行
https://raw.githubusercontent.com/opencv/opencv_3rdparty/${FFMPEG_BINARIES_COMMIT}/ffmpeg/
将FFMPEG_BINARIES_COMMIT
替换为文件顶部定义的值197f87f7e811a9ded35d989b37e50501ff6afaa4
,并添加下载文件名,
最终下载链接为:
https://raw.githubusercontent.com/opencv/opencv_3rdparty/197f87f7e811a9ded35d989b37e50501ff6afaa4/ffmpeg/opencv_videoio_ffmpeg.dll
粘贴到浏览器下载,其他几个文件同理。
最后,将ffmpeg.cmake
文件中https下载链接替换为文件下载地址:
file:///D:/Code/libraries/opencv_downloads/
再次用cmake
生成工程就可以了。
